Providing an escape sequence for Criteria queries
-------------------------------------------------

         Key: HHH-2077
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2077
     Project: Hibernate3
        Type: Improvement

  Components: query-criteria  
    Versions: 3.1.3, 3.2.0 cr1, 3.2.0.cr2, 3.2.0.cr3, 3.2.0.cr4    
 Environment: Hibernate 3.1.3, MySQL, HSQLDB, Oracle
    Reporter: Tobias Dietl


Up to now, there is no way of setting the escape sequence to use for string comparisions with like for Criteria queries. 

This is necessary as MySQL on the one hand and HSQLDB / Oracle on the other behave differently...

If you want to search for '_abc' in MySQL, you have to use:
    value like '\\_abc'

In Oracle or HsqlDB, you have to use:
   value like '\_abc'

If you want to switch to another escape sequence like '|' , you can set it in HQL with value like '|_abc' escape '|'. Unfortunately, there is no way of setting it for Criteria queries, which would force me to rewrite all my Criteria queries in HQL. It would really be nice if the feature/improvement would be added...
